libpmem1 1.12.1-2 (arm64 binary) in ubuntu mantic

 libpmem provides low level persistent memory support. In particular, support
 for the persistent memory instructions for flushing changes to pmem is
 provided.
 .
 This library is provided for software which tracks every store to pmem and
 needs to flush those changes to durability. Most developers will find higher
 level libraries like libpmemobj to be much more convenient.
 .
 This package provides binary runtime for version 1 of the API.
